given that its in the public domain (written earlier this month!) no copyright was violated in the process. since im the actual author and im not even renaming it, here is a mini version of logo in < 100 ploc of bash. it would have more features, but i was just having some fun. (and yes, i know what it says in proginf because i put it there.)
